( Ampere,Kw atau Watt )
Atau mungkin ada yg masih bingung tentang penghitungan atau rumusnya ,,,
Jangan salah penghitungan daya mungkin buat sebagian orang susah
ada juga yg bilang gampang yg pentingsih kemauan untuk belajar berikut yg bikin menghitung daya itu menjadi lebih mudah silahkan lansung DISINI
DC amps to kilowatts calculation
The power P in kilowatts (kW) is equal to the current I in amps (A), times the voltage V in volts (V) divided by 1000:
P(kW) = I(A) × V(V) / 1000
AC single phase amps to kilowatts calculation
The power P in kilowatts (kW) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V) divided by 1000:
P(kW) = PF × I(A) × V(V) / 1000
AC three phase amps to kilowatts calculation
Calculation with line to line voltage
The power P in kilowatts (kW) is equal to square root of 3 times the power factor PF times the phase current I in amps (A), times the line to line RMS voltage VL-L in volts (V) divided by 1000:
P(kW) = √3
× PF × I(A) × VL-L (V) / 1000
Calculation with line to neutral voltage
The power P in kilowatts (kW) is equal to 3 times the power factor PF times the phase current I in amps (A), times the line to neutral RMS voltage VL-N in volts (V) divided by 1000:
P(kW) = 3 × PF × I(A) × VL-N (V) / 1000
